INSOLE RIB ATTACHING MACHINES United States Patenti() i INSOLE RmATTACHING MACHINES Stephen P. Lotarski, Beverly, and Francis R. Speght,Dedham, Mass., assignors to United Shoe Machinery Corporation,Flemington, NJ., a corporation of New lersey Application June 24, 1958,Serial No. 744,123 9 Claims. (Cl. 12`20) This invention relates tomachines foi attaching strips to work pieces and is illustratedherein'as embodied in a machine for attaching ribbed strips to insolesto provide sewing ribs thereon of the typeA disclosed in a copendingUnited States application Serial No. 677,331, tiled August 9, 1957 inour names, now Patent No. 2,898,614, issued August 11, 1959. It is to beunderstood, however, that in its broader aspects the invention is notthus limited to that particular type of machine norV to the attachmentof that type of strip.

In accordance withv usual procedure in attaching ribbed strips toinsoles, the operation commences at the heel breast line at one side ofan insole, where thele'ading end vof a strip drawn from a source ofsupply is attached, then progresses along the margin of the insole atthat side toward the toe end and, after rounding the toe end, continuesalong the margin at the opposite side to a point located at the heelbreast line at that side of the insole. In the interest of both goodshoemaking and economy of material, it is desirable that the attachingoperation be terminated at a point located substantially in transversealinement with the starting point', It will be appreciated, however,that such a result requires'considerable skill and the closest attentionon the part of the operator, a requirement not easy of fulfillment inoperating a machine at high speed.` To enable the machine to producethis result automatically there is provided, in the machine disclosed inUnited States Letters Patent No. 2,670,480, issued March Y2, 1954 in thename of Alfred S. Clark, means for automatically stopping the feed ofthe vstrip when the attaching operation reaches a point at one side ofthe insole in transverse alinement with the starting Vpoint at theopposite side of the insole. The means in question comprises a pair offingers normally maintained vin parallel relation and of which the outerfinger is normally in contact with a microswitch carried by the innerlinger to maintain the microswitch open. During the at-`r taching of thestrip along the starting margin of the insole the two iingers are heldjust above the upper surface of the insole body inwardly of the rib.When the attaching operationalong the opposite margin of the insolereaches the shank portion, where the insole narrows, the fingers engagethe top of the rib at the v*side of the insole to which the rib was irstattached, and ride on'the rib until the outer one ofthe pair of .fingersdrops off, Vwhereupon the-microswitch is closed and energizes a solenoidwhich is connected to :the upper portion of a two-part treadle rod todisconnect the treadle and disengage a clutch which controls the stripfeeding mechanism.

AIt has been found that with this arrangement, when regions oftheinsole, is apt to engage the rib and be moved up out of parallelrelationrwith the outeriinger, thereby causing the microswitch to beclosedand actuating the ,mechanism to stop the feed of the stripbefrethe attachving operation has reached the desired point.

It is an object of the present invention to provide improved means ofthe type above described for automatically stopping the feed of a ribbedstrip at a point where the two ends of the strip will be in substantialalinernent transversely of the insole, irrespective of differences insizes or styles of insoles operated upon.

To this end and in accordance with a feature of the invention, there isprovided a single nger one end of which is adapted to engage the top ofthat portion of a ribbed strip which has been attached to one margin ofan insole at a time in an operating cycle when the attachment of thestrip along the opposite margin of the insole reaches the shank portionof the insole. At its opposite end the finger is secured to an armpivoted on a pin on which is also pivoted a second arm parallel to thefirst, or finger arm and having mounted thereon a normally closedmicroswitch which is maintained open by contact therewith of the fingerarm when the two arms are in parallel relation. The two arms arearranged to swing in unison in one direction about their common pivot tomaintain them in parallel relation when' the Vrib engaging end of thefinger rides up the top of the rib, and to swing individually relativelyto each other in the opposite direction when the rib engaging end of thelinger drops oi the rib. As will hereinafter appear in more detail, whenthe finger drops ofi the rib and is moved out of contact with themicroswitch, the microswitch is closed and energizes a solenoidconnected by a rod to the upper part of a twopart treadle rod whichactuates a lever which controls the operation of the presser and feedfoot of the machine. Energization of the solenoid disconnects the twoparts of the treadle rod and causes the previously mentioned lever tomove to a position in which it stops the operation of the presser andfeed foot.

To insure that, when the finger arm swings downwardly as the fingerdrops ofi the rib, the microswitch arm will be held against swingingmovement in the same directionl and thus prevent closing of themicroswitch by the swinging movement of the finger arm out of contacttherewith, there is provided, in accordance with ,another feature of theinvention, means for locking the Vmicroswitch arm in its raised positionafter it has been moved upwardly with the finger arm when the fingerengages the top ofthe rib, and for maintaining it thus locked untilafter the feeding motion of the presser and feed foot has stopped. Asherein illustrated, an upwardly extending latch member is pivotallyconnectedv to the microswitch arm and has a notch with which a detent,secured to a bracket on which the microswitch arm and the finger arm arepivoted, is arranged to engagewhen the arms are vswung upwardly byupward movement of the finger arm `to engage the top of the rib. As thesolenoid is operated supply at the end of an attaching operation, themachine of the present invention, like the machine of the applicationpreviously referred to, is provided withA a knife operated by a solenoidenergized when the operator closes a switch by actuating a knee lever.In accordance with a lfurther feature ofthe invention there is provided,in addition to the operator 'controlled means for rendering the lmifeeffective, automatic knife operating means which 1s renderedieiiectiveby the means previously described foriautomatic'ally stopping the'feeding and attachment of a rlbbed strip and in timed relationthereto.VAs herein illustrated, the'knife actuating solenoid is connected in acircuit comprising a microswitch which is normally held open by contacttherewith of that end of the feed control lever which is connected tothe upper part of the two-part treadle rod, the microswitch being closedby movement of the lever out of contact with it when the treadle isdepressed to start an attaching cycle. The above-mentioned circuitcomprises a time delay relay which energizes the circuit at apredetermined time after operation of the lever to stop the feed motionsof the presser and feed foot, so as to prevent any interference with theoperation of the knife or possible damage to it.

A selector switch permits the operator to connect the knife operatingsolenoidto either the circuit controlled by the feed control lever forautomatic knife operation, or to the circuit controlled by theoperator-actuated knee lever. Normally the latter will be used only inthe event of failure of the automatic system.

The machine is provided with a base 20 (Fig. 1), on the top of which isbolted a head 22 on which are mounted the various operatinginstrumentalities of the machine. In a bracket 24 xed to the base 20 ismounted a slide Z6, to which is secured a table 28 in which is mounted aroll 30 arranged to support and assist in feeding an insole I (Fig. 2)to which a strip Sdrawn from a source of supply (not shown), is to beattached. The strip S is progressively fed into engagementl with themargin of the insole and pressed thereagainst by-a presser and feed foot32, which also feeds the combined insole and attached strip. The presseryand feed foot 32 is secured to a lever 34 pivoted at 36 to a slide38movable horizontally in an arm 40 fixed to a sleeve 42 mounted on ashaft 44 which, through connections more fully described in UnitedStates Letters Patent No. 2,573,683, issued November 6, 1951 to FredericE. Bertrand, imparts reciprocating vertical movements to the foot 32 topress the strip against the insole. The lever 34 is also pivoted at 46to a bracket 48 on a link 50 connected by an arm 52 to the shaft 44,whereby reciprocating horizontal movements are imparted to the foot 32to feed the strip and insole. Y Y

A two-arm lever 54, pivotedsubstantially midway its aps-3,144.

length on a shaft 56 supported in the machine head, has a pin-and-slotconnection at its lower end to the slide 38. In the upper end of thelever 54 is provided a slot 58 through which extends a stud 60 carryinga roll 62 with which is arranged to engage a cam portion 64 of a lever66 fulcrumed about midway its length on a shaft 68 supported in abracket 70 secured to the machine head. The lever 66 is connected by alink 72 to the upper end of the upper section 74 of a two-part treadlerod, the lower section 76 of which extends through a bracket 78 securedto the machine head 22 and is connected at its lower end to a treadle(not shown). To the upper end of the lower treadle rod section 76 issecured a pawl 80 which is normally in engagement with a pawl 82 securedto the upper section 74 of the treadle rod, whereby the treadle rod maybe pulled downwardly as a unit.

When the treadle rod sections 74, 76 are pulled down by depression ofthe treadle, the lever 66 is swung in a clockwise direction, as seen inFig. 2, and its cam portion 64, acting on the roll 62, causes the lever54 to swing in the same direction about the shaft 56, against theresistance of a tension spring 83 attached at one end to the machinehead 22 and at its opposite end to a pin 84 extending from the lever 54.Clockwise movement of the lever 54 causes the slide 38 to move to theleft of Fig. 2 and the lever 34 to turn counterclockwise about the pivot46 to move the presser foot 32 to the right, adjacent to the deliveryside of a guide 85 through which the strip S is fed, so that the presserfoot may be in position to press the leading end of the strip againstthe margin of the insole prior to commencing its oscillatory motion topress and feed the strip and the insole. Depression of the treadlecauses engagement of a clutch (not shown) to impart to the presser andfeed foot 32 movements in an orbital path in a manner more fullydescribed in the Bertrand patent previously referred to.

As explained above, it is desirable that the operation of the presserand feed foot 32 be automatically stopped when the operation reaches apoint along the margin of antinsole substantially in transversealinement with the point to which the strip has been rst attached at theopposite margin of the insole. For this purpose there is provided alinger 86 (Figs. 1, 2 and 3) which, at the beginning and during themajor portion of an attaching cycle, is spaced just above the bodyportion of the insole inwardly of the margin to which the strip isattached and which, as will hereinafter appear, is arranged, when vtheoperation reaches a point near the shank portion of the insole at theside opposite that to which the strip has first been attached, to engagethe top of the rib portion of the strip and to remain in engagementtherewith until the attaching operation reaches a point substantially intransverse alinement with the starting point.

The finger 86 is secured in a block 88 (Figs. l, 2 and 3) having asliding t in a groove formed in a block 90 for adjustment of the fingeraxially of the roll 30 to vary the location of the finger in accordancewith variations in the shank widths of different insoles. The block 90extends transversely of the machine and is mounted in a groove providedinV a bracket 92 for adjustment of the finger forwardly or rearwardly ofthe machine with relation to the presser and feed foot 32 to varythelocation of the finger in accordance with the speed atrwhich themachine is operated to feed the strip and insole. The block 90 issecured in adjusted position by a screw 94 extending through a slot 96in the bracket 92.

The bracket 92 has a tongue and groove connection to one end of an arm98 (Figs. 3, 4, 9-11), the other end of which is fulcrumed on a pin 100mounted in a bracket 102 secured to the machine head 22. The bracket 92is adjustable heightwise relatively to the arm 98 kfor adjustment of thefinger 86 heightwise with relation to the insole supported on the Vtable28, and is secured in adjusted position by a set screw 104. On the pin100 is also fulcrumed oneV end of an arm 106 parallel to the speak/i4arm 98 and carrying a rnicroswitch 108 having a springpressed button 109with which the arm 98 engages to maintain the microswitch normally open.In the opposite bifurcated end of the arm 106 is pivotally mounted anupwardly extending latch lever 110 having a notch 112 formed in itsupper end portion and with which, as will be explained, is adapted toengage a detent 114 secured to the bracket 102. 1 j e l Referring toFigs. 1, 2 and 3, the upper treadle rod section 74 extends through aboss 116 on a horizontal rod 118 extending laterally of the machine head22. The forward or right-hand end of the rodV 118 extends through ablock 120 secured to the machine head 22 and has thereon a nut V122 anda Washer 124 between which and the block 120a spring 126 is mounted onthe rod 118. :The rear or left-hand end of the rod 118 isconnected tothe core 128 of a solenoid 130 connected inan electric circuit shown Vinthe wiring diagram, Fig. 13, in which circuit', is also connected `thernicroswitch 108.

The mechanism heretofore described for automatically stopping theoperation vof thev presser and feed foot 32 operates in the followingmanner. When the machine is started to begin an attaching operation, thepresser e the insole, as illustrated inFig. 6.- On an insole for a rightshoe the operation commences at theV outside shank portion. Q,

, As the presser and feed foot32 executes its orbital motion to pressthe strip and feed the work, the finger 86, which is located in theproximity of the foot 32, is

spaced just abovethe upper surface of the insole inwardly of the marginto which the strip is being attached.y

After the presser andi feed foot has rounded the toe portion of theinsole and as the operation reaches the shank portion on the outside`margin of thel insole, where the insole narrows, the finger 86 is causedto move up onto the top of the 'rib portion R of the strip, as shown inFig. 7, and, remains ,in engagement therewith as the attaching operationprogresses toward the heel end of the insole `until a point on theinsole is reached that is substantially in transverse alinement withthe' starting point, whereupon the finger drops oif the rib portion, asshown in Fig. 8.

When the finger 86 moves up onto the rib portion of the strip, the arm98 swings about the'pin 100 clockwise, as seen in Fig. 10. As moreclearly shown in Fig. 4, a stud 132 is threaded into the arm 98 and hasthereon a nut and a washer 134 Yextending across thefundersurfaces ofboth armsv 98 and 106, so that when the arm 98 yswings clockwise, aspreviously explained, the arm 106 v 'which carries the rnicroswitch 108is caused to swing in (see Fig. ,10) to lock the arm 106 in its raisedposition A so that the rnicroswitch 108 will be closed when the fingerv86 'drops oif the Vrib portion R of the strip at the sidewhere thestrip was frst attached, as shown in Fig. 8, and the iing'erfarm 98swings in a counterclockwise or downward direction, as seen in Fig. 11,out of parallel relation with the rnicroswitch arm 106vand away from'the rnicroswitch button 109. Closingofthe microswitch- 108, energizesthe solenoid 130 which pulls the rod 11S' to the left, as viewed inFigs. 2 and 3, against the resist- A`e ance of the spring 126, therebydisconnecting the upper treadle rod section 74 from the lower section76. The

treadle rod section 74 is then moved upwardly from they link 72 and atits other end to a pin 141 projecting from `the machine head 22. Upwardmovement of the rod section 74 is limited by an abutment 142 adjustablysecured by screws 144 to the machine head 22. The lever 66 is therebycaused to swing in a counterclockwise direction, as seen in Fig. 2,about the shaft 68 to stop the mechanism which operates the presser andfeed foot 32 even though the operator should continue to hold thetreadle depressed. When the rod 118 moves to the left, as previouslyexplained, a striker 146 adjustably secured to the rod 118 by screws 148engages the upper end of the latch lever and causes the lever to swingout of engagement with the detent 114, against the resistance of atension spring 150 (Figs. 3 and 9-l1) secured at one end to the latchlever and at its other end to a member 152 secured to the bracket 102,the spring tending norinally to maintain the latch lever in engagementwith the detent. The arm 106 to which the latch lever 110 is connectedis thusrfree to swing downwardly (or counterclockwise, as seen inFigs..3 and 1l) about the pin 100 into parallel'relation with the arm 98with the result that this arm again presses the button 109 of the switch108 to reopen the switch for a succeeding strip attaching cycle, oftheemachine. vDownward swinging movement of thearms 98 and 106 islimited by a pin 153 (Fig. 4) extending from the bracket 102.

For severing the strip at the end of an attaching cycle, the machine isprovided with a knife 154 (Figs. l and 12) movable transversely of theinsole between the strip guide 85 and the presser and feed foot 32. Theknife is adjustably secured to a carrier 156 which is connected by a rod158, a bell crank 160 and a rod 162 to the-core 164 of va solenoid 166housed in the base 20 of the niachine. The solenoid may be energized bya manually operatedmicroswitch 168 actuated by a rod 170 connected by arod 172 to a knee pad 174. However, inV

accordance with a feature of the present invention, the solenoid 166 mayalternatively be energized automatically bythe rnicroswitch 108 which,as previously explained, is closed by movement of the finger 86 off therib portion of the strip attached to the insole to stop the feeding'Ymechanism at a predetermined point in an attaching Vthe lever 66 whichcontrols the operation of the presser and feed fot 32 so that, with thelever 66 in the position of Fig.Y 1, the switch 176 is maintained open.When the treadle is depressed to start an attaching cycle and the lever66 turns clockwise, as seen in Fig. 2, the microswitch 176 is closed fora purpose which will appear as the description proceeds. A torsionspring mounted orrthe pin 184 and bearing at one end against the under-Jsurface of the rnicroswitch 176 and at its other end ferator to connectthe ,solenoid 166 to either the automatic control circuit for automaticoperation of the knife or to the microswitch 168 for manual operation.It will VVbe understood that the latter will be used only as an 7auxiliary means in case of failure of the automatic mechanism. l

Operation of the means for automatically stopping the strip attachingand feeding mechanism at a predetermined point in a machine cycle andfor operating the knife to sever the strip will now be described, withparticular reference to the wiring diagram in Fig. 13. In thisdescription it will be assumed that the machine is at rest and that theselector switch 192 has been turned to the Automatic position to permitconnection of the severing knife operating solenoid 166 to the powerline marked A.

With the electric motor running and an insole having been placed on thetable 28 (as shown in Fig. 2) and located in proper position for a stripVattaching operation by means of an edge gage 194 (Fig. 12), when theoperator depresses the treadle to engage the clutch, the lever 66 turnsclockwise, as seen in Fig. 2, and the microswitch 176 which, aspreviously explained, is normally held open by engagement of the leverwith the roll 188, is closed.

When the attaching operation reaches the shank portion of the insole atthe side opposite that at which the attaching began, the finger 86 movesup onto the rib portion of the strip, and continues in engagement withit as the attaching operation progresses rearwardly toward the heel endof the insole. During that time the microswitch 108 is held open byvengagement of the finger arm 98 with the microswitch button 109 since,as previously explained, the two arms 98 and 106 swing upwardly inunison and the microswitch arm 106 is held in elevated position by thelatch lever 110. When the attaching operation reaches a point at theheel breast line substantially in transverse alinement with the startingpoint and the finger 86 drops olf the rib portion of the attached strip,the microswitch 108 is closed.

Closing of the microswitch 108 energizes a relay K1 (Fig. 13), closingnormally open contacts Kl-A and Kl-B and opening contacts Kl-C. Theclosure of contacts Kl-A completes a pair of holding circuits for therelay K1, one of said circuits including the microswitch 176 and theother circuit including the normally closed contacts TD2-B. The openingof contacts Kl-C prevents the establishment at this time of a circuitthrough the knife operating solenoid 166.

The closure of contacts Kl-B energizes the solenoid 130 by which the rod118 is moved first to disengage the latch lever 110 by which themicroswitch arm 106 was locked in its raised position, whereupon the arm106 drops and the button 109 of the switch engages the finger arm 98 toopen the microswitch.

Immediately after releasing the latch lever 110 the rod 113 disengagesthe upper treadle rod section 74 from the lower section 76, whereuponthe lever 66 moves back to its inoperative position, opening themicroswitch 176. The relay K1 is not de-energized at this instantbecause of the holding circuit through the contacts Kl-A referred toabove. Y

Simultaneously with the energizing of the solenoid 130 by closure of thecontacts Kl-B a relay TD1 is energized through these same contacts. Thisrelay is aV time delay relay in which the contacts controlled therebyare immediately operated by energization of the relay, but return totheir normal positions only after a predetermined time followingde-energization of the relay. Thus, upon energization of the relay TD1contacts TD1-A immediately closeand contacts TD1-B immediately open. Theclosure of contacts TDll-A completes a circuit through a second timedelay relay TD2. Energization of the relay TD2 opens contacts TD2-B, sothat both holding circuits through the relay K1 are de-energized andaccordingly the relay K1 is de-energized, whereupon its contacts Kl-Cagain close. No circuit, however, is completed at this time through thesolenoid 166 because contacts TD1-B have opened. Energzation of relayTD2 causes immediate closure of contacts TD2-A.

The circuits through the relays TD1 and TD2 are interrupted as soon ascontacts Kl-B are open by reason of the de-energization of the relay K1.The contacts TD1-B of the'relay TD1 now move to closed position, butonly after a predetermined time delay, so that the solenoid 166 by whichthe knife is operated is not energized until the pressure and feed foothas had time to get out of the way of the knife, thereby to preventpossible damage thereto. The contacts TD2-A of the time delay relay TD2are arranged to open shortly after contacts TD1-B have been closed,thereby to interrupt the circuit through the solenoid 166, immediatelyafter operation of the knife to sever the rib. This completes a cycle ofoperations of the machine and the parts are all in the positions shownin Figs. 1 and 13. It will be understood that the time delay periods ofthe relays TD1 and TD2 are very short and that the entire cycle ofoperations, following closure of the switch 108, is completed veryrapidly.

If for any reason the automatic system of Fig. 13 should fail, theoperator may turn the selector switch 192 to the Manual position,whereupon the knife operating solenoid 166 may be operated by pressingon the knee pad 174 to close the microswitch 168.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent of the United States is:
